COSMETIC COMPOSITIONS AND ME'THOD OF USING THE SAME
Technical Field
[0001] The disclosure is in the field of cosmetic
compositions for treating aging skin,
and with particular efficacy in stimulating synthesis of collagen in skin
cells.
Background of the Disclosure
[0002] Collagen is one of the main structural proteins in
skin. It can be found in the
fibrillar or non-fibrillar form. The fibrillar form is most common and
includes collagen
subtypes I, II, III, V. and XI. Types I, IV, and V are most often associated
with skin and
dermal tissue. Collagen found in the skin typically diminishes with age and
causes laxity,
lines, and wrinkles on skin. Any active ingredient that induces skin cells to
increase collagen
synthesis is desirable because it ameliorates the adverse effects of collagen
deficiency in skin
cells which causes lines, wrinkles, and skin laxity.
[0003] It has been unexpectedly discovered that an extract
obtained from Hibiscus
genus in combination with an extract obtained from Moringaceae genus
synergistically
improved stimulation of collagen synthesis in skin cells. And it has also been
unexpectedly
discovered that a complex of actives further synergistically improved the
efficacy of the
combination of the extract obtained from Hibiscus genus and the extract
obtained from
Moringaceae genus on stimulating collagen synthesis in skin cells.
Summary of the Disclosure
[0004] The disclosure is directed to a topical composition comprising an
extract from
Hibiscus genus and an extract from the Moringaceae genus.
[0005] The disclosure is also directed to a topical
composition comprising an extract
from Hibiscus genus, an extract from the Moringaceae genus, and a complex of
actives

PCT/US2022/049175
[0017] Hibiscus sinensis flowers deploy their corolla in the
morning, when the flowers
are stained with an ivory white color. Over the course of the day, the petals
become
increasingly pink, and they are an intense pinkish red at the end of
flowering. Thus white or
light pink Hibiscus sinensis flowers are considered as young flowers, and red
Hibiscus
sinensis flowers are not considered as young flowers. The preferred Hibiscus
sinensis flowers
are young flowers (i.e., white flowers and/or light pink flowers).

more preferably
from about 0.01 to 2%, most preferably from about 0.1 to 1% by weight of the
total
composition.
[0029] Plants from this genus grow prevalently in Africa and
India. Moringaceae is a
genus of flowering plants that vary in size from large trees to small
flowering plants. There
are 13 species. The species drouhardii, hildebrandtii, ovalifoli a, and
stenopetala are massive
trees with large water storing trunks ("bottle trees") and small radial and

6
CA 03237001 2024-5- 1
WO 2023/086305
PCT/US2022/049175
The species concanensis, oleifera, and peregrina are slender trees with a
tuberous juvenile
stage and pale white or pink flowers. The species arborea, borziana,
longituba, pygmaea,
rivac, ruspoliana in the form of trees, shrubs, or herbs. Moringaceae olcifera
in particular is a
fast-growing tree that is often referred to as the "drumstick tree".
Moringaceae leaves are said
to contain high amounts of vitamins, polyphenols and four unique sugar
modified aromatic
glycosides. Isothiocyanates from Moringaceae (or Moringaceae isocthiocyanates
(-MIC"))
are said to have many health benefits. In general, isothiocyanates are formed
when an
enzyme, myrosinase (aka thioglucoside glycohydrolase), cleaves thio-linked
glucose in
precursor glucosinolates. Moringaceae extracts with higher concentrations of
MICs are most
desirable. Such extracts can be prepared by injuring the plant parts to cause
an increase in the
myrosinase enzyme content, which in turn will promote conversion of
Moringaceae
glucosinolates ("MGL") into MICs.
[0030] Moringaceae extracts that may be used in the
compositions of the invention are
further described in Phytochemistry, Vol 103 (2014), pages 114-122; and U.S.
provisional
patent application serial nos. 61/898795 filed November 1, 2013; 62/032496,
filed August 1,
2014; and U.S. Serial No. 14/683730, a continuation-in-part of
PCT/US2014/0063178, filed
October 30, 2014, all being incorporated by reference in their entirety.
[0031]
Injuring the plant parts can occur by processing steps such as pressing,
slicing,
pulverizing, crushing, blending, or grinding. Injury (and myrosinase
production) can also be
induced by subjecting the plant parts to a solution containing water. This
solution may be all
water, or a mixture of water of various solvents such as ethanol, propanol,
isopropanol,
butylene glycol propylene glycol, pentylene glycol, and so on. It is preferred
that such injury
occur at temperatures lower than 100 C. and without otherwise exposing the
plant parts to
extreme weather conditions such as low temperatures or harsh drying
conditions. The
conditions inducing plant injury should take place for a period of time
sufficient to activate the
7
CA 03237001 2024-5- 1
WO 2023/086305
PCT/US2022/049175
myrosinase enzyme in an amount sufficient to cause increased production of
MICs in the
injured plant parts.
[0032] The plant parts that may be used include stems,
leaves, roots, sprouts, seeds,
twigs, flowers, bark, etc. Most preferred is where the plant parts that are
injured are from
seeds, sprouts, or leaves. It is preferred that the plant parts are fresh,
that is, they have not
been dried or frozen.
[0033] After injury of the plant parts, they may be extracted
or dried. Suitable
extractants may be water or mixtures of water and solvents as noted above. The
injured plant
parts may be extracted immediately, or extracted after drying.
[0034] Suitable extractants include water, alkanes, ethers, aromatic
solvents, ketones
and the like. Preferred is water alone, water/solvent mixtures, or solvent
alone where the
solvents comprise mono-, di-, or polyhydric alcohols such as ethanol,
propanol, isopropanol,
butanol, methanol. The extractant may be combined with the plant parts in any
suitable ratio
including 1:1-10 to 1-10:1 ratio of solvent/water respectively.
[0035] It is preferred that the concentration of MIC in the extract should
be at least 0.5
to 10% of MICs per gram of plant material, preferably 0.75 to 4%, more
preferably from 0.8 to
5%. Harsh temperatures or drying of plant parts will cause rapid degradation
of the MICs
present in the plant parts and resulting extract.
[0036] Most preferred is Moringaceae oleifera seed extract
containing from about 0.5
to 3.0% MICs, more preferably 0.75 to 2.5% MIC, most preferably from about 0.8
to 1.5%
MICs. This extract may be purchased from Nutrasorb LLC under the trade name
Nutringa0
which is mixture of Moringaceae oleifera seed extract and isoceteth-20 in a
ratio of about 7.5
to 92.5 respectively, and containing about 1% MIC. The MIC content of the best
embodiment
extract when tested for stability at 25 C. and 37 C. for 30 days is greater
than 65%,
preferably greater than 70%.

old donor
were plated onto 6 well plates at a density of 50,000 cells/well and incubated
at standard
conditions (37 C/ 5% CO2) overnight. Fibroblasts were grown in DMEM media
supplemented
with 10% Bovine Calf Serum and 1% Penicillin Streptomycin.
[0096_1 Comparable extracts were made from flowers being harvested at
different times
and extracted with the same process. Comparable Extract A was obtained from
young
Hibiscus sinensis flowers (Hibisculineg from SILAS). Comparable Extract B was
made from
dark pink Hibiscus sinensis flowers. And Comparable Extract C was obtained
from red
Hibiscus sinensis flowers.
[0097] The samples were treated with Comparable Extract A, B, or C at their
active
dosages of 0.0021%, 0.0105%, or 0.021% in fully supplemented media. The plates
were
incubated at standard conditions (37 C/ 5% CO2) for 96 hours. Following
incubation,
supernatants were harvested and stored at -80 C.
[0098] After 96 hours incubation and supernatants were
collected, cell counts were
performed for cell viability. Each sample was washed once with PBS and then
administered
0.25% trypsin. After cells detached from the 6 well plates, media was
administered to each
sample to neutralize the trypsin. Cell counts were done with the Vice11.
[0099] Collagen I production was assessed using the Pro
Collagen Type I ELISA
(Takara MK101) per vendor's protocol (Takara Bio, MK101). The optical density
(OD) was
measured at 450 nm.

[01011 This experiment showed the critical importance of
harvesting time when it
comes to plants extracts and this precision is essential in order to deliver
the best performance
to the skin. The extract from young Hibiscus sinensis flowers (white flowers
and/or light pink
flowers) showed the significantly better efficacy of stimulating collagen
production at all
active concentrations.
Example 2
[0102] Composition samples were tested for their ability to
stimulate collagen
production in normal human dermal fibroblasts ("NHDF"). NHDF from older donors
(a 61
year old and a 62 year old) were plated onto 6 well plates at a density of
50,000 cells/well and
incubated at standard conditions (37 C/ 5% CO2) overnight. Fibroblasts were
grown in
DMEM media supplemented with 10% Bovine Calf Serum and 1% Penicillin
Streptomycin.
[0103] The composition samples were made from the ingredients
and at the
concentration listed in the table below and numbered as follows: (1) Extract
of Hibiscus
sinensis; (2) Extract of Hibiscus sinensis, and Extract of Moringa Oleifera;
(3) Extract of

Moringa Oleifera, Complex of Actives (Acetyl Hexapeptide-8, Extract of
Laminaria Digitata,
and Whey Protein); (4) Extract of Hibiscus sinensis, Extract of Moringa
Oleifera, Complex
of Actives (Acetyl Hexapeptide-8, Extract of Laminaria Digitata, and Whey
Protein).
INCI Name Active Dose (%)
Extract of Hibiscus sinensis 0.021
Extract of Moringa Oleifera 0.005

[0104] The control and samples were tested in fully supplemented media. The
plates
were incubated at standard conditions (37 C/ 5% CO2) for 96 hours. Following
incubation,
supernatants were harvested and stored at -80 C.
[0105] After 96 hours incubation and supernatants were
collected, cell counts were
performed for cell viability. Each sample was washed once with PBS and then
administered
0.25% trypsin. After cells detached from the 6 well plates, media was
administered to each
sample to neutralize the trypsin. Cell counts were done with the Vicell.
[0106] Collagen I production was assessed using the Pro
Collagen Type I ELISA
(Takara MK101) per vendor's protocol (Takara Bio, MK101). The optical density
(OD) was
measured at 450 nm.
[0107] Statistical analysis was performed on all samples using one-way
ANOVA with
a post test of Dunnett's in Graphpad InStat. The results are set forth below:
Collagen I Production Standard Error (SEM) % Increase in collagen production
Control 3.04E-03 2.09E-04
Sample 1 4.83E-03 2.01E-04 59%
Sample 2 1.77E-02 2.83E-03 483%
Sample 3 1.85E-02 1.56E-03 510%
Sample 4 3.00E-02 2.09E-03 888%

[0108] While Extract of Moringa Oleifera itself does not have
activity in stimulating
collagen production, Extract of Hibiscus sinensis induced a 59% increase in
collagen
production. Further, the combination of Extract of Hibiscus sinensis and
Extract of Moringa
Oleifera synergistically induced a 483% increase in collagen production.
Additionally, the
combination of Extract of Hibiscus sinensis, Extract of Moringa Oleifera and
the Complex of
Actives induced a 888% increase, while the combination of Extract of Moringa
Oleifera and
the Complex of Actives only induced a 510% increase.
